The pressure of the gas is 3.52 atm

<u><em>calculation</em></u>

This is calculated using the Boyle's law formula

that is P1V1= P2V2 where;

P1 = 1.65 atm

V1 =22.8 L

P2 =? atm

V2 = 10.7 L

make P2 the subject of the formula by dividing both side by V2

P2 = P1V1 / V2

P2 = (1.65 atm x 22.8 l) / 10.7 L = 3.52 atm

2L of hydrogen has an initial pressure of 750 mmHg, what is the final pressure in mmHg if the volume increases to 20 L with a co

Verdich [7]

Answer: The final pressure is 75 mm Hg.

Explanation:

According to Boyle's law, at constant temperature the pressure of a gas in inversely proportional to volume.

Since, it is given that the temperature is constant. Hence, formula used is as follows.

$P_{1}V_{1} = P_{2}V_{2}$

Substitute the values into above formula as follows.

$P_{1}V_{1} = P_{2}V_{2}\\750 mm Hg \times 2 L = P_{2} \times 20 L\\P_{2} = \frac{750 mm Hg \times 2 L}{20 L}\\= 75 mm Hg$

Thus, we can conclude that the final pressure is 75 mm Hg.
